Hi, I have fittet a gamma model, and is wondering if I can read the shape and
the scale direct from the summary  

                           Estimate     Std. Error    t value    Pr(>|t|)    
(Intercept)              1.612e+00  4.735e-02  34.052   <2e-16 ***
myvalue                  3.564e-02  2.787e-03  12.788   <2e-16 *** 
...

Is the shape = 1.1612e+00
and the scale = 3.564e-02 ??

is it the other way around, or can't it be done?

To glm is

glm(log(mydata)~log(max_data)*as.factor(grp),family=Gamma(link="log"))

And I was wondering if you can read the scale and shape from summary



There a quite a few "gamma models" around, so you should tell us more.
glmXXX? lmer?
